In Reply to: Dearborn 10-1 3 bottom plow question posted by pat redington on June 21, 2017 at 13:52:48:
First, congrats on the buy -$23, what deal! Next, the Dearborn Prior Model Plows never offered a 3-bottom version. That plow is a farmerized plow with a 3rd beam attached-see the angle iron on top??? That ain't original. N's can't pull a 3-bottom. Not sure which U-Bolt you refer to but there is a cam-locked adjustment U bolt on the cross shaft -see here. From our MANUALS forum we have the Assembly & Operating Manual plus the Master Parts Catalog for free download...CLICK ON LINK BELOW
